Rapid has previously installed six bespoke concrete batching plants over the last forty years at Tobermore’s County Londonderry headquarters. This seventh Rapid plant will enable Tobermore to meet a surge in market demand.
The new Rapid batching plant is comprised of a 20m3 dump hopper to receive aggregates and sand and an inclined 750mm-wide conveyor to convey materials to the shuttle conveyor. The shuttle conveyor distributes aggregates to each of the aggregate bins. Aggregates and sands are stored in a series of 29 storage bins, of varying sizes, from 4.7 – 100m3.
Two 600mm and one 750mm weighed belt conveyors collect materials from the aggregate and sand storage bins and discharges these to the main transfer conveyor, leading to the changeover tower. From the changeover tower, the materials are transported to the mixer house via a 750mm-wide inclined batch conveyor. The batch of aggregates is then subsequently distributed via a diverter chute to each of the holding hoppers, until required by the mixers. Three 150tonne silos feed the mixer via the screw conveyors.
A series of six wet batch hoppers under the face mix and four hoppers under the back mix, offers a huge range of blending combinations.
The multifloor mixer platform design allows maximum access for cleaning and maintenance. Designed to house the plant’s two integral mixers, the platform is also sized to accommodate the travelling wet batch hoppers (backing and face hoppers).
